Embodiment Construction

[0016]It was surprisingly found that the surface life fatigue and surface degradation rate of a mechanical component could be modeled. It was also surprisingly found that surface life fatigue and surface degradation rate could be predicted and characterized.

[0017]The system and method of the present invention are useful in predicting the surface life fatigue or surface degradation rate of mechanical components that are subject to repeated, cyclical mechanical and / or thermal stress. The system and method are useful, for example, with gears, bearings, splines, and springs. The system and method are particularly useful with interlocking / intermeshing gears, which are subject to repeated, cyclical mechanical stress. The system and method can be used with any type of gear, such as but not limited to a spur gear, worm gear, straight bevel gear, Zerol bevel gear, spiral bevel gear, helical gear, herringbone gear, double helical gear, hypoid gear, crossed helical gear, and the like.

Abstract

There is a method for modeling the surface fatigue life of a mechanical component. The method has the following steps: a) modeling the surface fatigue life of the mechanical component on an atomistic scale to form an atomistic model, b) modeling the surface fatigue life of the mechanical component on a mesoscale to form a mesoscale model, c) modeling the surface fatigue life of the mechanical component on a macroscale to form a macroscale model, and d) testing the surface fatigue life of the mechanical component. Feedback from the macroscale model is employed at least once to validate the atomistic model. Feedback from the macroscale model is employed at least once to validate the mesoscale model. Feedback from the testing is employed at least once to validate the macroscale model. There is also an interactive, multiscale model for prediction surface fatigue life or degradation rate for a mechanical component.
